More Details on Our Top Picks
40 Gallon RV Fresh and Gray Water Holding Tank
This 40-gallon water tank stands out for its large capacity and flexible installation options, making it ideal for varied camper setups. Compared with the smaller Camco RhinoFaucet, this tank’s size provides more water for longer trips, though it demands careful venting and sealing to prevent leaks or pressure issues. Its NSF-approved, food-safe materials ensure safe drinking water, and the ability to position it in any orientation offers unmatched adaptability. However, its size and weight mean it’s less suited for users seeking lightweight or ultra-compact solutions. This pick makes the most sense for campers who prioritize high capacity and installation flexibility over portability.
Pros:- Large 40-gallon capacity for extended use
- Made from NSF-approved, safe materials
- Versatile installation with adjustable orientation

This 33-gallon tank fits perfectly over van wheel wells, making it an excellent choice for maximizing space in Sprinter, Transit, and ProMaster conversions. Unlike the bulkier 40-gallon tanks, it offers a compact solution that integrates seamlessly with van interiors, although it requires careful handling during installation to avoid damage. Its impact-resistant polyethylene construction guarantees durability on rough roads, and being BPA-free ensures safety for drinking water. The main tradeoff is that it cannot be pressurized or hung with straps, meaning users must handle it gently and maintain it regularly through rinsing.

Unlike longer hoses, it offers a compact solution for handling black water, making it suitable for smaller setups or emergency use. Its durable vinyl and UV-stabilized resin ensure longevity, and the swivel fittings help secure connections quickly.

Its sturdy construction and included accessories make setup straightforward, though its weight can be a challenge for less experienced users. While ideal for most RV sanitation needs, it’s not suited for other waste management scenarios. This kit is best for those seeking a reliable, organized solution for regular sewer hookups.

It’s well-suited for users needing to transport waste over varied terrains, with the built-in gate valve simplifying disposal. Unlike smaller tanks, its 28-gallon capacity offers a good balance for regular use without becoming overly heavy, though it still weighs 43 lbs when full.

This tank is best for those who want a durable, portable waste solution that can handle rougher environments.

Camco RhinoFLEX 20-Ft Complete RV Sewer Hose Kit
The Camco RhinoFLEX 20-Ft Complete RV Sewer Hose Kit stands out for offering a complete, flexible solution for managing waste during longer trips. Compared with the Rhino Ultimate 20′ Kit, it provides the same length but includes two hoses with pre-attached fittings, making setup quicker and more straightforward. Its durable polyolefin construction ensures longevity, while the compact storage size makes it easy to stow in your bumper. However, the assembly required for storage and its weight might challenge some users, especially when carrying or setting up alone. This kit is ideal for RVers who prioritize a comprehensive, all-in-one sewer solution and don’t mind a bit of initial setup. It’s less suited for those seeking ultra-lightweight gear or minimal setups for short trips. Pros include durable, flexible materials; all necessary fittings included; and compact storage design. Cons are the assembly needed for storage and potential heaviness. Verdict: This kit makes the most sense for RV owners needing a reliable, all-in-one sewer hose system for extended camping adventures.

- Hoses:2 x 10 ft hoses
- Fittings:Pre-attached, 360° swivel

Camco Deluxe 10-Foot RV Sewer Hose Extension
The Camco Deluxe 10-Foot RV Sewer Hose Extension is a practical choice for RVers who already own a sewer setup like the RhinoFLEX kit but need extra length for tricky hookups. Its heavy-duty vinyl material offers excellent flexibility and durability, while the swivel REVO fittings make connecting and disconnecting straightforward. Compared with the full-length RhinoFLEX kit, this extension is less versatile but excels in adding length without complexity. Its compact design and pre-attached caps help contain odors and simplify storage, though it lacks additional accessories such as clamps, which might be necessary for a secure fit. It’s a good fit for RV owners who require a quick, reliable extension rather than a complete sewer system. Those seeking an all-in-one solution or lighter gear should look elsewhere. Pros include durable, flexible construction; swivel fittings ease the process; and space-saving design. Cons are the absence of clamps or extra accessories and the potential weight of heavy-duty material. Verdict: This extension makes the most sense for RV owners needing to extend their existing sewer setup with a durable, reliable option.

- Material:Heavy-duty vinyl
- Fittings:Swivel REVO fittings
- Made in:USA

Factors to Consider When Choosing Can For Camper Conversion
Choosing the right can for your camper conversion involves considering several factors that impact usability, longevity, and overall convenience. It’s not just about capacity but also about how well the tank fits your camper’s layout and your maintenance preferences. The following considerations will help you avoid common pitfalls and make a more informed decision tailored to your camping style.Capacity and Size
Consider how much water or waste you need to store. Larger tanks reduce the frequency of emptying but can be difficult to install or move. Smaller, portable tanks are easier to handle but may require more regular maintenance. Measure your available space carefully and choose a size that balances capacity with installation feasibility to avoid space constraints or frequent emptying trips.
Material and Durability
Look for tanks made from high-quality, BPA-free plastics or other durable materials that resist cracking, UV damage, and chemical degradation. Cheaper materials may save money upfront but often lead to leaks or deteriorate faster, increasing long-term costs. Consider the environment where you’ll camp most often—UV resistance and robustness are especially important in sunny, outdoor conditions.
Compatibility and Fit
Ensure the tank fits your camper’s layout and connection points. Fixed tanks like the 40-gallon model are best for permanent setups, while portable tanks like the Rhino series offer flexibility. Check dimensions and connection types—some tanks are designed specifically for certain RV models or van conversions, so verify compatibility before purchasing.
Ease of Maintenance and Use
Simplicity in draining, cleaning, and refilling is vital for ongoing convenience. Tanks with built-in valves and easy-access ports reduce hassle. For waste tanks, look for features like heavy-duty wheels or handles that make moving them less taxing. Remember, a well-designed tank minimizes messes and reduces the risk of leaks or failures over time.
Cost and Value
Prices vary widely based on capacity, material, and features. While it’s tempting to opt for the cheapest option, investing in higher-quality tanks often pays off in durability and ease of use. Balance your budget with your needs—sometimes spending a bit more on a reliable, well-made tank prevents costly repairs or replacements later on.
Frequently Asked Questions
What size water tank should I choose for my camper conversion?
The ideal size depends on your camping style and space constraints. If you plan to camp for several days without hookups, a larger tank, such as 40 gallons or more, provides more independence. For shorter trips or limited space, smaller tanks around 20-30 gallons can be sufficient and easier to install. Always consider your vehicle’s available space and your water usage habits when selecting size.
Are portable tote tanks better than fixed tanks for camper conversions?
Portable tanks like the Rhino series excel in flexibility—they can be moved for cleaning or emptying, making maintenance easier. Fixed tanks are more permanent, often offering larger capacity and a cleaner aesthetic, but require more effort to install and remove if needed. Your choice depends on how often you want to handle the tank and your space limitations—if frequent emptying is expected, portable might be better.
What materials should I look for in a durable camper water tank?
High-quality, BPA-free polyethylene or similar plastics are common choices for their durability and safety. These materials resist cracking, UV damage, and chemical wear. Avoid tanks made from thinner plastics or recycled materials that may degrade faster. Investing in a robust material reduces the risk of leaks, contamination, and the need for early replacements.
Can I install a water or waste tank myself?
Many tanks are designed for DIY installation, especially smaller portable options with straightforward connection points. Fixed tanks may require some plumbing skills and tools, but with proper guidance, many enthusiasts manage the installation themselves. Always follow manufacturer instructions carefully to ensure leak-proof connections and proper venting, and consider consulting a professional if unsure about plumbing specifics.
What features should I prioritize in a sewer hose kit?
Look for flexibility, length, and durability. Kits with longer hoses like the RhinoFLEX 20-Ft provide more reach, reducing the need to reposition the RV during emptying. Heavy-duty materials resist cracking and punctures, while features like bayonet fittings ensure secure connections. Easy storage options and compatibility with your existing setup also matter, as they simplify maintenance and reduce setup time.
Conclusion
The best choice depends on your specific camper conversion needs. For overall reliability and capacity, the 40 Gallon RV Fresh and Gray Water Holding Tank offers a solid solution for full-time campers. Those prioritizing portability and ease of maintenance will find the Camco Rhino 28-Gallon Tote Tank ideal. Beginners or casual campers should consider smaller, simpler tanks to avoid complications, while experienced DIYers might prefer customizable or larger fixed tanks. For waste management, pairing durable sewer hose kits like the RhinoFLEX with a well-sized tote tank ensures a smoother, more efficient setup. Ultimately, selecting the right can balances your space, usage, and budget for a successful camper conversion.
